CONTROLS

DC Inverter ControlProvides continuous operation, while adjusting capacity according to room temperature.The accurate sensing of cooling or heating loads prevents frequent changes in capacity and ensures efficient, economical operation.Outdoor Unit MicroprocessorElectronic expansion valve control (all models except MS7-HO-30P).Automatic compressor timed-off protection (3 minutes).Automatic fan delay in heating mode (heat pump models) after coil is warm.Temperature sensor.LEDs on control (09-24 models) or two-digit character display (30 model) display error codes and assist in troubleshooting.Communication port to indoor unit.4-way valve control (heat pump models).Electronic Expansion ValveFurnished on all models except MS7-HO-30P. MS7-HO-30P uses a capillary system.Compressor Overcurrent ProtectionOvercurrent protection can result due to any of the following:• The ambient temperature is too high• Locked rotor on the compressor• Outdoor air is blocked or restrictedCondenser High Temperature ProtectionCondenser high temperature can occur due to any of the following conditions:• High outdoor ambient• Outdoor fan blocked• Outdoor coil blockedThe outdoor coil thermistor continuously monitors the temperature and communicates with the microprocessor.Depending on the temperature measured, the compressor will be allowed to increase the frequency if needed to meet the load or is forced to run at the current or reduced frequency. If the temperature gets excessively high the compressor will be de-energized as shown below:When the outdoor coil temperature drops to 124ºF, the unit will resume normal operationsNOTE - In heating mode (heat pump models) the indoor fan is de-energized 60 seconds after the compressor is de-energized.

High Pressure Discharge Temperature ProtectionThe compressor discharge temperature can be high due to any of the following:• Low refrigerant charge• Blocked capillaryThe compressor discharge line thermistor continuously monitors the temperature and communicates with the microprocessor.Depending on the temperature measured, the compressor will be allowed to increase the frequency to meet the load or is forced to run at the current or reduced frequency. If the temperature gets excessively high, the compressor will be de-energized. When the compressor discharge temperature drops below 194ºF, the unit will resume normal operations.Intelligent Power Module (IPM) ProtectionProtects the unit from any of the following conditions:• Loss of cooling to the heat sink• High ambient temperature• Low voltageLow Voltage ProtectionIf the incoming voltage is below the minimum allowed, E5 will be displayed on the front panel of the indoor unit.Terminal StripFurnished for easy wiring connections.Defrost Control (Heat Pump Models)Defrost cycle is automatically enabled if there is a build-up of frost on the outdoor coil. Outdoor fan and indoor blower operation is terminated during the defrost cycle.H1 is displayed on the indoor unit panel on the front cover during a defrost cycle.Reversing Valve (Heat Pump Models)4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover from cooling to heating and vice versa.Valve operates on pressure differential between outdoor unit and indoor unit of the system.

temperature is less than 75°F there is a three-minute time delay before blower runs at low speed for five minutes.

• If coil temperature is equal to or more than 106°F and room temperature is equal to or more than 75°F blower runs at low speed for five minutes.

FILTER

Cleanable filter furnished as standard.

CONTROLS

Indoor Unit MicroprocessorContains all necessary components to control system.Terminal StripFurnished for easy wiring connections.Indoor Coil Freeze ProtectionWhen the unit is operating in the COOL or DEHUMIDIFICATION MODE, the indoor coil may freeze due to any of the following:• Low system charge• Reduced indoor airflow• Restricted refrigerant flow• Low ambient temperature (outdoor)• Low load (indoor)The indoor coil thermistor monitors the coil temperature continuously. Any time the coil temperature drops below 30°F, the compressor and the outdoor fan (30 seconds later) will be switched off until the coil temperature rises above 43°F and the compressor was off for a minimum of 3 minutes.Auto Button OperationIf the wireless remote control is lost, damaged, or the batteries are exhausted, the AUTO button located inside the front cover on the indoor unit can be used to run the unit.Auto Settings:• Cooling Mode (setpoint 77°F)• Heating Mode (setpoint 68°F)• Fan Only Mode (runs continuously)• Fan Speed (Auto)• Oscillate (On)

SpeediChannel™ System

SpeediChannel™ is a channel system used to cover system line sets. The two-part system has a base and a cover. The base is fastened to a wall or ceiling with plastic clips (SpeediClip™) that snap into a channel already molded into the base. The cover fits on top of the base. SpeediChannel is manufactured from rigid PVC, which is UL rated and resistant to UV light. The system is a natural color that closely matches typical mini-split outdoor units. However, it can be painted as desired to match any wall color.

SpeediChannel™ System (CONTINUED)

SpeediChannelTM Starter Kit The starter kit includes (1) Coupling, (1) Wall Penetration, (1) Inside Elbow, (1) Long Radius Flat Bend, (10) SpeediclipsTM, (10) 11 in. Cable Ties, and (1) SpeediChannel Instruction Booklet.Duct End Duct Ends are used to terminate a run of SpeediChannel™ to a small opening just large enough for the line set and condensate drain line to pass through. Flat Wall EscutcheonFlat Wall Escutcheons are used to cover a rough opening in a soffit, wall, or ceiling penetration. One side of the escutcheon

is flat to allow for a SpeediChannel™ to run along a wall and to penetrate through an adjacent wall or ceiling. This is the most common type of wall penetration. Furnished in two parts, the escutcheon easily snaps onto the SpeediChannel™.

Flex JointA Flex Joint is an accordion-style piece of SpeediChannel™. The flex joint can be extremely flexible when routing a SpeediChannel™ system around an obstacle. Each joint is 20 in. long and can be combined together for longer flex runs. The flex joint does not require the use of a union coupling. The flex joint slides tightly inside the SpeediChannel™ system. T-JointT-Joints are used for creating a tee connection between three pieces of SpeediChannel™. Each tee is individually packed and furnished with stainless steel screws.

Union CouplingUnion Couplings are used for joining two pieces of SpeediChannel™. Each coupling is individually packed and furnished with stainless steel screws.

Wall Penetration CoverWall penetration covers are used to transition from the SpeediChannel™ system to a through wall penetration. Wall covers are designed to allow for easy installation, even after the line set has been installed. A hooking and fastening arrangement allows for quick installation. Each wall cover is individually packed, and furnished with stainless steel screws to attach the wall cover to the base. Three screws are necessary to fasten the wall cover to the wall construction, regardless of the type of installed system. 45° and 90° Flat Bend Elbows45º Flat Bends are used to route the SpeediChannel™ around obstacles. Each bend is individually packed and furnished with stainless steel screws.

90° Inside Elbow90º Inside Elbows are used to route the SpeediChannel™ around an inside corner. Each elbow is individually packed and furnished with stainless steel screws.

Mount Block White Qty. (2) 14 in. and (2) 36 in.Mount Blocks are used as mounting bases when outdoor units must be bolted down. End caps (for aesthetics) come furnished with mounting bolts. Maximum load capacity is 900 pounds per mounting block. Installation temperatures range from -4ºF to 140ºF. Mount blocks fit all mini-split outdoor units with a sliding rail feature.
